FYI cache lines are 64 bytes, not bits. So Apple is using 128 bytes. Also important to consider that the RTX 4090 has a relatively tiny 384-bit memory bus. Smaller than the M1 Max's 512-bit bus. But the RTX 4090 has 1 TB/s bandwidth and significantly more compute power available to make use of that bandwidth. |

The M4 max is definitely not a 4090 killer, does not match it in any way. It can however work on larger models than the 4090 and have a battery that can last all day.
My memory is a bit fuzzy, but I believe the m3 max did decent on some games compared to the laptop Nvidia 4070 (which is not the same as the desktop 4070). But highly depended on if the game was x86-64 (requiring emulation) and if it was DX11 or apple native. I believe apple claims improvements in metal (the Apple's GPU lib) and that the m4 GPUs have better FP for ray tracing, but no significant changes in rasterized performance.
I look forward to the 3rd party benchmarks for LLM and gaming on the m4 max.
